It's just a thought Matt. I have been looking at and buying these Yaskawa drives and motors for a while, probably 2 years now, and there are always plenty to choose from and in a few years time when the latest generation ones come up for resale you will get servo's with 1 million counts per rev for the same price and same frame size and maybe a little bit more powerful.
You can download all the manuals from Yaskawa still and they are pretty comprehensive as you would expect.
